Revit 2018 Licensing System Error 2

[gadangit]

I recently got a Licensing System Error 2 when launching Revit 2018. My 2017 and 2019 work just fine. I've followed the instructions for completely removing Revit 2018 and all associated files. After downloading and re-installing I get the same error. I've been using 2018 for years, so not sure what changed. Revit 2018 will work as unregistered.

I'm on a Windows 10 machine.

I've tried fixes of the same error for 2017 and 2019, but nothing seems to work.

Not sure what you have come across but have you seen this

I did find that.  And tried to implement the 2018 version of the fix (it was for 2017, 2019).  But it didn't change anything after re-install.

At this point I have followed the complete un-install instructions for revit 2018.  I changed up the downloader to browser to see if I got a different set of files from the last time.  Ran the installer, hit launch and got the same Licensing System Error 2 when choosing sign in.  The program will not even let me run an unregistered version any longer as the "Run" button is grayed out.  

I opened Revit 2017 and 2019 and it did a license check and sent me an email thanking me for registering?  So something has changed.  I'm at a loss of what to do next.

I realize this is an older post, but if anyone else has the issue, I found I had LogMeIn installed an creating issues.  See here:  https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Error-...

Nothing worked for me until I followed these instructions, then I was able to sign into my license again (had to reinstall licensing service.)
